Q # 13. please help to solve this

Answer 1

To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
 A=2πrh+2πr^2
 Where r is the radius and h is the height of the cylinder
 You have that r=15.1 inches and h=12.8 inches, then:
 A=2πrh+2r^2
 A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2 
 A=2647 in^2
 The answer is 2647 in^2
